Q:

What is a sporophyte?

A:

Quick Answer

A sporophyte is a plant or alga in its diploid multicellular stage of life that produces spores. Each sporophyte has a double set of chromosomes, one from its haploid egg cell and another from its haploid sperm. The resulting fertilization produces a zygote from which the sporophyte develops. Most land plants, as well as many algae plants, are sporophytes.

Full Answer

The spores that the sporophyte produces are asexual. In order to survive, the spores must produce these gametophytes by way of meiosis. These gametophytes are also asexual with one set of homologous chromosomes. According to Reference.com, the sporophyte is an important feature of a plant life cycle; the spores produced by the sporophytes develop into gametophytes, which will produce male and female gametes that reproduce with its opposite gamete to produce a zygote. This zygote will in turn develop into another sporophyte. A sporophyte's life span varies, depending on the plant. In mosses, they are relatively long-lived, and they live even longer in seed plants. They are easily visible as shapes similar to capsules with plant stems, and an embryo sporophyte is visible in an opened seed often in a cone-like shape. Depending on the type of moss, the sporophytes on moss are more covert, but they are rounder and less distinctly shaped than their seed plant counterparts.

  • Q:

    What is on a plant life cycle diagram?

    A:

    A plant life cycle diagram shows a sporophyte plant create a spore that grows into a gametophyte plant that releases gametes, which then combines with another gamete to form the embryo of another sporophyte plant. The exact details of these different stages vary greatly between groups of plants.

  • Q:

    How is the fern life cycle similar to the moss life cycle?

    A:

    The fern life cycle and moss life cycle are similar in that they have alternation between sporophyte and gametophyte stages and that both rely on layers of water so that their sperm can swim from one gametophyte to the eggs of another. This means that both ferns and mosses require relatively moist environments. They are also similar in that their gametophyte stage, unlike other plants, does not rely on sporophytes.

    How do you grow mushrooms in cow dung?

    A:

    To grow mushrooms in cow dung, mix the dung with mushroom spores, pour the mixture into a grow box, add peat moss when the spores begin to grow, cover the moss with a moistened newspaper and remove the paper once the mushrooms sprout. Irrigate the mushrooms regularly until they mature.
